When we speak about Middle and Long Distances, from 800m to Marathon, we always must remember that are event of extension. Better, events of SPECIFIC EXTENSION.
We can classify the type of training we have to use in very simple way, looking at the speed, the duration and the goals :
1) REGENERATION, with the goal to better and faster recover the real training
2) FUNDAMENTAL, having the goal to create the aerobic base for putting in training workouts of higher intensity
3) SPECIAL, being the DIRECT SUPPORT of the Specific Training
4) SPECIFIC, that HAS DIRECT INFLUENCE on the performance
The problem for every athlete is :
HOW IS IT POSSIBLE TO BETTER SUPPORT THE SPECIFIC TRAINING, and the percentage of it inside the global volume we use.
